Garlic Butter Sweet Potato Bake Ingredients
For the Sweet Potatoes
• Sweet Potatoes – Use orange-fleshed varieties for the best sweetness and creaminess.
• Kosher Salt – Essential for seasoning; salt between layers to enhance flavor.
• Black Pepper – Freshly cracked for added warmth and spice.
For the Sauce
• Heavy Cream – Provides a rich, creamy texture; swap for half-and-half for a lighter option.
• Unsalted Butter – Adds a depth of flavor; avoid salted butter for better control over saltiness.
• Garlic – Fresh minced garlic imparts the best flavor; steering clear of pre-minced ensures freshness.

Step‑by‑Step Instructions for Garlic Butter Sweet Potato Bake
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms up, take a 9×13-inch baking dish and grease it liberally with butter or cooking spray to prevent sticking. This will ensure that your Garlic Butter Sweet Potato Bake comes out easily, revealing those beautifully caramelized layers of sweet potatoes.
Step 2: Create the Garlic Butter Sauce
In a medium saucepan over medium-low heat, whisk together cornstarch and heavy cream until blended. Add in the unsalted butter, minced garlic, and fresh thyme. Stir gently as the butter melts and the mixture heats up, being careful not to let it boil. You should see it gently steaming in about 5 minutes, filling your kitchen with a delightful aroma.
Step 3: Slice the Sweet Potatoes
While the garlic butter sauce is heating, take your sweet potatoes and slice them into 1/8-inch thick rounds. A mandoline slicer works wonderfully for this to ensure uniformity, which promotes even cooking. As you slice, place the rounds in a large bowl, then season lightly with kosher salt and black pepper to enhance their natural sweetness.
Step 4: Layer the Sweet Potatoes
Arrange the sliced sweet potatoes in the greased baking dish, overlapping them slightly to create an appealing pattern. This not only looks gorgeous but also helps retain moisture as the Garlic Butter Sweet Potato Bake cooks. Aim for even layering so that every bite is filled with delicious flavor.
Step 5: Pour the Sauce
Once your garlic butter sauce is ready, carefully pour it evenly over the arranged sweet potatoes. Use a spatula to ensure every slice is coated in this rich, creamy mixture. This step is crucial for achieving that luxurious texture you desire in your Garlic Butter Sweet Potato Bake.
Step 6: Initial Bake
Place the baking dish in the preheated oven and bake uncovered for 30 minutes. During this time, the sweet potatoes will soften and absorb flavors while the sauce thickens. You’ll want to check that the sweet potatoes are tender but not falling apart by pricking them with a fork.
Step 7: Add Parmesan Topping
After the first baking phase, take out the dish and sprinkle the grated Parmesan cheese generously over the top. This addition is what transforms your Garlic Butter Sweet Potato Bake into a golden, bubbly masterpiece. Return it to the oven for an additional 10 minutes until the cheese is melted and bubbly with a beautiful golden crust.
Step 8: Broil for Crispiness
For an extra touch, switch your oven settings to broil and put the bake back in for a final minute or two. This will create a perfectly crispy cheese topping that adds delightful texture to your dish. Keep a close eye on it, as broiling can quickly change from golden to burnt.
Step 9: Rest Before Serving
Once done, remove the baking dish from the oven and allow it to rest for about 10 minutes. This resting period helps the sauce thicken, making it easier to slice and serve. Your Garlic Butter Sweet Potato Bake is now ready to be enjoyed alongside your favorite main course!
